2017-10-10hdat: Disable TM on Power9 DD 2.1Michael Ellerman1-1/+1
Update pa_features_p9[] to disable TM (Transactional Memory). On DD 2.1 TM is not usable by Linux without other workarounds, so skiboot must disable it. The presence of TM is communicated by setting bit 7 of byte 22 in the pa-features array. As no other bits are set in that byte, we currently have a value of 0x80. To disable TM we set bit 7 to 0, leaving a value of 0x0. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2017-10-10FSP/NVRAM: Handle "get vNVRAM statistics" commandVasant Hegde1-0/+41
FSP sends MBOX command (cmd : 0xEB, subcmd : 0x05, mod : 0x00) to get vNVRAM statistics. OPAL doesn't maintain any such statistics. Hence return FSP_STATUS_INVALID_SUBCMD. Sample OPAL log: [16944.384670488,3] FSP: Unhandled message eb0500 [16944.474110465,3] FSP: Unhandled message eb0500 [16945.111280784,3] FSP: Unhandled message eb0500 [16945.293393485,3] FSP: Unhandled message eb0500 With this patch, I don't think FSP will ever call "free vNVRAM" MBOX command. But to be safer side lets return FSP_STATUS_INVALID_SUBCMD for this MBOX command as well.

2017-10-10pci-iov: free memory across fast-rebootStewart Smith3-6/+26
pci_set_cap needs a callback to free data and we need to call that when we're doing __pci_reset() We also need to free pcrf entries. In the future, __pci_reset() and pci_remove_bus() need to come together to be one canonical place on how to free a PCI device rather than the two we have now. This patch *purely* focuses on the problem of not leaking memory across fast-reboot. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2017-10-06external/gard: Clear entire guard partition instead of entry by entrySuraj Jitindar Singh1-11/+18
When using the current implementation of the gard tool to ecc clear the entire GUARD partition it is done one gard record at a time. While this may be ok when accessing the actual flash this is very slow when done from the host over the mbox protocol (on the order of 4 minutes) because the bmc side is required to do many read, erase, writes under the hood. Fix this by rewriting the gard tool reset_partition() function. Now we allocate all the erased guard entries and (if required) apply ecc to the entire buffer. Then we can do one big erase and write of the entire partition. This reduces the time to clear the guard partition to on the order of 4 seconds.

2017-10-02phb4: Reassign link_retries counter in IODA purgeGuilherme G. Piccoli1-0/+2
Recently, a link_retries counter was added in pci/phb4 in order Skiboot can retry to train a link some times - default number of attempts to retrain a link is 3. Happens that, if during a regular boot process we exhaust the link retries and fail to train a PHB, the variable link_retries is stuck in 0. If a kdump happens later, a PHB reset procedure is triggered by Linux and, since we have a decrement-and-test in this variable, we end up setting it to -1; it's unsigned, hence we get an overflow. This patch fixes the issue by reassigning the default value to link_retries in every IODA purge. Signed-off-by: Guilherme G.
